I was reading about Arthas recently, and it dawned on me that the high elves did not come to aid the humans in Lordaeron when they were being decimated by Arthas and his forces. I read this on Wowpedia's article about Anasterian Sunstrider, the High King of the elves:
Still reigning over Quel'Thalas at the time of the Third War, despite his advanced age, Anasterian spared little thought for the plight of the humans in Lordaeron; true to the past, believing it to be a human issue than the high elves would not deign to trouble themselves with.
To me, it doesn't make sense why he would do this. He was proved wrong in the past when he believed that the humans' problems were not his own, and he and his people paid very dearly for his apathy on this second occasion. Can anyone elaborate on why he and/or his people did not aid the humans in Lordaeron against the Scourge?
It seems also that Arthas took a while in Northrend chasing Mal'Ganis and getting corrupted by Frostmourne and killing his men. Not to mention what seems to be a fairly large distance between Northrend and Lordaeron: http://cl.ly/image/1n0x0p0B2x1p. It seems as though that would have been enough time for the elves to realize that something was up in Lordaeron.
